Chau has already spent $20 and needs to spend at least $30 in total on gifts. We can represent this situation with the following inequality:
\[ 20 + c \geq 30 \]
To solve for \( c \), we can subtract 20 from both sides:
\[ c \geq 30 - 20 \]
\[ c \geq 10 \]
So, the inequality that represents the possible additional amounts Chau will spend is:
\[ c \geq 10 \]
This means Chau needs to spend at least $10 more on gifts.
\[ 20 + c \geq 30 \]
To solve for \( c \), we can subtract 20 from both sides:
\[ c \geq 30 - 20 \]
\[ c \geq 10 \]
So, the inequality that represents the possible additional amounts Chau will spend is:
\[ c \geq 10 \]
This means Chau needs to spend at least $10 more on gifts.
